OREDA handbook 5th edition
The fifth edition of the OREDA andbook was released in 2009 and is split into two volumes:
Volume 1 – Topside equipment
Volume 2 – Subsea equipment
As focus in OREDA has been on collecting subsea data in the phases from which data in these books originate, less topside data have been collected than in past OREDA phases. To obtain a reasonable population for presenting reliability data for topside equipment in the 2009 edition, some data issued in the previous 2002 handbook (4th edition) have also been included. The 2002 edition included data collected during OREDA phase IV and V (1993ñ1999).
Compared to the 2002 edition, there are some minor changes in the reliability data presentation. For the subsea volume, however, data is presented at more detailed taxonomy and application levels than the 2002 issue. The main changes are:
Active repair time and restoration man-hours are both given with their mean and maximum values
Failures modes and corresponding failure rates are given for each subunit / component and each severity class both for the whole equipment unit and equipment unit subdivided in relation to application
Failure mechanisms (previously termed Failure Descriptor) are given for each failure mode. The number of these failures categorised as Critical and Degraded, plus totals, are summarised separately.

What is new
Most importantly, the 5th edition of the OREDA handbook includes data from phases VIII IX and X. In these phases, the data collection has been focused on subsea equipment. An overview of the content of the various handbooks can be found in the table and the graph below.
|2||1992||I – III|
|3||1997||III – V|
|4||2002||IV – V|
|5||2009||IV – VII|
A new release of the OREDA handbook (6th edition) is planned and under development. It will be published upon the completion of the current OREDA phase, XI, which is scheduled in 2015/2016.
How to use the OREDA handbook
The OREDA 2009 handbook will give you a unique data source on failure rates, failure mode distribution and repair times for equipment used in the offshore industry. Such data are necessary for reliability as well as risk analyses.
Possible applications are:
- Reliability, Availability and Maintainability (RAM) analyses
- Regularity studies.
- Risk analyses.
- Planning and scheduling of maintenance, inspection and testing.
- Cost benefit studies.
- Selection of alternative system designs.
